Dimensionality of the SIS Support Needs Scale (Section 1) was examined in reference to the three areas of conceptual, social, and practical skills reported by the American Association on Mental Retardation as comprising the adaptive behavior construct. Factor analysis of the adaptive behavior subscales and SIS Support Need Scale offered support for measurement of a common underlying construct. When considered in terms of the three adaptive behavior skill areas, this construct related predominantly to conceptual skills.enHumansAdaptation, PsychologicalSocial BehaviorMental DisordersSocial SupportAdultAgedMiddle AgedHealth Services Needs and DemandFemaleMaleIntellectual DisabilityJournal article002005097710.1352/0895-8017(2005)110[393:SNAAB]2.0.CO;20002317662000082-s2.0-2544448335554673Harries, J.
